Abstract
The invention relates to a novel water-soluble intermediate di (disubstituted amino) phenyl porphintetrapyrrole compound which is good in hydrophilicity, easy to prepare into an injection and simple and feasible in preparation process, and a preparation method of the tetrapyrrole compound shown in the description, wherein X is H, Cl, Br, or I; R is a meta-position or para-position group, and R is -N (R1) 2; R1 is -(CH2)nCOOH, and n is equal to 1-6; and R2 is 2H or Zn. The invention relates to the field of photosensitive drugs and photodynamic therapy, in particular to a novel intermediate di (disubstituted amino) phenyl porphintetrapyrrole compound which is good in hydrophilicity and easy to prepare into injection, a preparation method of the intermediate di (disubstituted amino) phenyl porphin tetrapyrrole compound and application of the intermediate di (disubstituted amino) phenyl porphin tetrapyrrole compound in the field of medicine. The intermediate di (disubstituted amino) phenyl porphin photosensitizer prepared by the invention has remarkable photodynamic activity and low skin light toxic and side effects, and can be used as a drug for photodynamic diagnosis and treatment of diseases such as tumors, retinamacular degeneration, actinic keratosis, nevus flammeus and condyloma acuminata.
Description
technical field [0001] The invention relates to the field of photosensitizing drugs and photodynamic therapy, in particular to a class of intermediary di(disubstituted amino)phenylporphine tetrapyrrole compounds with stable structure, simple and convenient preparation method, good hydrophilicity and easy preparation into injections and its Applications in the field of medicine. Background technique [0002] Photodynamic therapy (PDT) is a novel method for the treatment of tumors, macular degeneration, port wine stains and other diseases. After the photosensitizer enters the human body, under the irradiation of external light of a certain wavelength, it changes from the ground state to the excited state, generating free radicals and reactive oxygen species (ROS), which can cause direct damage to the lesion cells, and can also damage the blood vessels around the lesion. , thus blocking the supply of nutrients to the lesion and causing indirect damage. Compared with conventio...
